Description

Technical Field

[0001] This utility model relates to the field of locking mechanism technology, specifically to a locking buckle for an anti-loosening telescopic rod. Background Technology

[0002] Telescopic rods are mostly locked using levers or knobs. Lever locking is widely used because of its fast locking and unlocking speed, strong locking force, and high sturdiness. The rod and lever are connected by a threaded pin. During repeated locking and unlocking, the rod may rotate or wear may increase, causing the locking gap to lengthen and the locking force to decrease. If the user finds that the locking force is insufficient, the rod needs to be adjusted with tools. Frequent adjustments will greatly affect the user experience. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing an anti-loosening telescopic rod locking buckle.

[0004] This utility model includes a locking sleeve, an adjusting rod, a rotating shaft, a wrench, and a locking screw for the rod. One side of the locking sleeve is open, and a rod clearance hole is provided on the open side. One end of the adjusting rod passes through the rod clearance hole and is threadedly connected to the rotating shaft. One end of the wrench is provided with a rotating shaft mounting hole, and the rotating shaft is rotatably installed in the rotating shaft mounting hole of the wrench. The locking screw for the rod is screwed to one end of the rotating shaft and locks the adjusting rod.

[0005] The wrench located at one end of the shaft mounting hole has a cam structure, and the opening side of the locking sleeve is provided with an arc-shaped positioning groove that cooperates with the cam structure.

[0006] The rotating shaft is provided with a pull rod connection hole. One end of the adjusting pull rod is threaded to the pull rod connection hole. One end of the rotating shaft is provided with a locking screw mounting hole that communicates with the pull rod connection hole. The pull rod locking screw is threaded to the locking screw mounting hole and is pressed against one side of the adjusting pull rod.

[0007] The rotating shaft is provided with a pull rod connection hole. One end of the adjusting pull rod is threaded to the pull rod connection hole. There are two pull rod locking screws. Both ends of the rotating shaft are provided with locking screw mounting holes that communicate with the pull rod connection hole.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0016] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0017] In the description of the embodiments of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, if terms such as "first" or "second" appear in the description of this invention, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0019] As shown in the figure, this utility model includes a locking sleeve 1, an adjusting rod 2, a rotating shaft 3, a wrench 4, and a rod locking screw 5. One side of the locking sleeve 1 is open, and a rod clearance hole is provided on the open side. One end of the adjusting rod 2 passes through the rod clearance hole and is threadedly connected to the rotating shaft 3. One end of the wrench 4 is provided with a rotating shaft mounting hole, and the rotating shaft 3 is rotatably installed in the rotating shaft mounting hole of the wrench 4. The rod locking screw 5 is screwed to one end of the rotating shaft 3 and locks the adjusting rod 2.

[0020] The wrench 4 located at one end of the shaft mounting hole has a cam structure, and the opening side of the locking sleeve 1 is provided with an arc-shaped positioning groove that cooperates with the cam structure.

[0021] When the wrench 4 is turned, the rotational force is converted into linear pressure through the cam structure, thereby pulling the adjusting rod 2 upward and squeezing the opening side of the locking sleeve 1 to achieve locking.

[0022] The locking force is adjusted by changing the length of the adjusting rod 2. The adjusting rod 2 is threadedly connected to the rotating shaft 3. After connection, the adjusting rod 2 is prone to rotation during repeated use, which may cause it to loosen. The increased locking distance of the adjusting rod 2 will lead to a decrease in locking force. In this case, a rod locking screw 5 is screwed to one end of the rotating shaft 3. After the adjusting rod 2 is adjusted to the correct length, the rod locking screw 5 locks the position of the adjusting rod 2 from one side, which can effectively prevent the adjusting rod 2 from loosening during use.

[0023] In the first embodiment of the pull rod locking screw 5, the rotating shaft 3 is provided with a pull rod connecting hole, one end of the adjusting pull rod 2 is threadedly connected to the pull rod connecting hole, one end of the rotating shaft 3 is provided with a locking screw mounting hole communicating with the pull rod connecting hole, and the pull rod locking screw 5 is threadedly connected in the locking screw mounting hole and pressed against one side of the adjusting pull rod 2.

[0024] In a second embodiment of the pull rod locking screw 5, the rotating shaft 3 is provided with a pull rod connecting hole, one end of the adjusting pull rod 2 is threaded to the pull rod connecting hole, and there are two pull rod locking screws 5. The two ends of the rotating shaft 3 are respectively provided with locking screw mounting holes communicating with the pull rod connecting hole. The two pull rod locking screws 5 are symmetrically installed at both ends of the rotating shaft 3 and press the adjusting pull rod 2 from both sides respectively.

[0025] The two locking screws 5 tighten the adjusting rod 2 from both ends, making the locking more reliable.

[0026] Furthermore, a pull rod clamping block 6 is provided in the locking screw mounting hole. One end of the pull rod clamping block 6 is an arc-shaped concave structure that matches the outer side of the adjusting pull rod 2. The pull rod locking screw 5 locks the adjusting pull rod 2 through the pull rod clamping block 6.

[0027] The pull rod clamping block 6 is a movable part. Its arc-shaped concave structure can fit against the side wall of the adjusting pull rod 2 with the largest area. The pull rod locking screw 5 squeezes the pull rod clamping block 6, thereby making the pull rod clamping block 6 and the adjusting pull rod 2 tightly clamp together.

[0028] Furthermore, both the pull rod clamping block 6 and the pull rod locking screw 5 have screw slots at their ends. The screw slot of the pull rod clamping block 6 is preferably a slotted slot, with its direction corresponding to the arc-shaped concave structure, serving as a directional indicator and facilitating quick alignment of the arc-shaped concave structure onto the adjusting pull rod 2 during installation. The screw slot structure of the pull rod locking screw 5 is not limited; slotted slots, Phillips head slots, and hex sockets are all acceptable.
